To all whom t may concern.'

Be it known that I, ROBERT J. SMoTHERs,

Ia citizen of the United States, residing at CII Holyoke, in the countyof I'Iampden and State of Massachusetts, have invented certain new anduseful Improvements in Photographic-Printing Machines, of which thefollowing is' a specification.

rlhis invention relates to a photographic printing machine, moreespecially to what' may be termed a photo print linotype machine, andhas for its object to provide a 'machine of the class referred to,having means for assembling characters, designs or lin'iages insuccessive line-like arrangement,I

successively .printing photographically each assembled line upon asensitized surface of `the desired length and width, and then developingand fixing the print for use in 'connection with the subsequentproducing of a printing plate, capable of being employed in direct,odset, textile, color and rotogravure printing.

,YRFi-i-marily, a photo print linotype machine, in accordance with thisinvention, is designed. to dispense with the slug casting mechanism ofthe well-known linotype machine of commerce, as well as to dispense withthe subsequent laborious operation to produce from the casted slugs,avflat, a sectional cylindrical or a semi-cylindrical printing plate,and to substitutev therefor means to provide a photographic print to beutilized in the production of a light, durable, flat printing platecapable of beingdetachably connected `in cylindrical form to theprinting cylinder of the press, or fiat-wise to a job press, under suchconditions mate- -rially vexpediting the .printing operation,

overcoming the handling ofthe heavy forms and plates as now used, and;materially decreasing the costs now lpresent in the production of platesor rolls employed in direct, offset, textile, color and rotogravureprintlng. Y

In a photo print linotype machine, in acco1'dance"\vi th this invention,the well-known forms of matrices used in linotype machines are employed,but are so constructed to carry a character, design, or image, generallytermed an object which is photographically printed upon a sensitizedsurface. In the machine, in accordance with this''invention the functionof the well known linotype machme matrices is changed from that ofcasting to that of photographic printing, and

in view of this change in function, the matrices are termed phototypographie character slugs. The slugs are set up in successiveline-like arrangement, justified and distributed in the same manner asthe matrices,

in the well-known linotype machine. The slugs when assembled on the linebar, clamped and justified are positioned to provide forphotographically printing successively lines of aligned objects on thesensitized surface of a flexible strip of substantial width and length,after which the print is developed and fixed for the purpose referredto.

Further objects of the invention are to provide, a photo print linotypemachine, in a manner as hereinafter set forth and for the purposereferred to, and which is durable, thoroughly ehcient in its use,conveniently operated, readily assembled, and comparatively inexpensive.

With the foregoing and other objects in view, the invention consists ofthe novel construction, combination and arrangement of parts, ashereinafter more specilically described and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but 1t 1s to be understood lthat changes, variations and modificationscan be resorted to which come within the scope of the claims hereuntoappended.

A photo print linotype machine, in accordance with this invention, issimilar in construction and arrangement to the wellknown linotypemachines with this exception, that the slug casting mechanism of suchmachine is dispensed with and there is substituted therefor means toprovide a photographic print consisting of successive,

lines of aligned objects and which print is employed in the productionof a printing plate capable of being detachably connected to theprinting cylinder of a cylindrical printing press, or detachablyconnected in operative position in a job press. The well-known forms ofmatrices used in linotype machines are employed, but are so constructedto carry an object and to enable the printing of such objectphotographically upon a sensitized surface. In the machine, inaccordance with this invention, the function of the well-known matricesis changed from that of casting to that of photographic printing, and inview of this change in function, the matrices are termed phototypographie character slugs. are set up in successive line-likearrangement, on a line bar clamped and justified and thenpositioned toprovide for photographically printing a line of objects on thesensitized surface of a flexible strip of suitable material ofsubstantial width and length, and after the print is made, the slugs aredistributed to' their respective magazines. The setting up of the slugsin successive line-like arrangement, the clamping of the slugs, thejustifying of the slugs, the positioning of the slugs for printing, andthe distributing of the slugs is had in the same manner as is done withrespect to the matrices in the well-known linotype machines, and forsuch purposes the elements to perform such functions', ofthe well-knownlinotype machines, are employed. After the flexible strip has beenprovided with the desired number of lines of photographically printed`objects, the

These slugs aaaaeao said strip is developed and fixed, and then used inthe production of the printing plate.

' Each of the character slugs is constructed in the same manner as a.matrix of a linotype machine, with the following exception:--

'rits is well-known, a matrix of the type employed in iinotype machineshas its front edge provided with a pair of notches, suitably spaced fromeachother and with the base of each notch countersunk to form theoutline of a letter, but one of the letters is of a different style ortype to that of the other. 'lo provide for the utilization of thiswell-known type of machine, in accordance with this invention, the frontedge of the body portion of the matrix, which is notched, is cut outintermediate its ends to extend slightly beyond each of such notches andto a substantial depth, and within said cut-away portion is arranged acarrier provided with the object to be photographed. The sides of thebody of the matrix are grooved. @ther than` that as stated, theconstruction of a photo ytypographie character slug employed in amachine in accordance with this invention is similar to that of thewell-known matrix of a linotype machine. 'lfhe photo t vpographiccharacter slug employed will be hereinafter specifically described.

As the means employed in a machine, in accordance with this invention,for assemf bling, justifying, positioning and distributing the.character slugs is identical in constructon as employed in thewell-known linotype machines, such means will be generally referred toas it is thought unnecessary to specifically describe the same.

A photo print linotype machine, in accordance with this invention,comprises means for assembling in line-like arrangement character slugs,justifying the line of slugs, positioning the line of slugs for pho--tographically printing thepbjects carried thereby and distributing theslugs to their respective magazines after the print has been made, a webroll magazine, a signal oralarm to indicate the breaking of the web asit unwinds from the roll, a main housing, a shutter and shiftingmechanism therefor, a light source, a web pressing and light controllingmechanism, web feeding mechanisms, a cutter mechanism, a line or workstop indicator, a web conveyor mechanism, and a photographic printdeveloping and fixing mechanism.

Referring toFigures 1 and2 of the drawings, when the machine is employedin the customary manner, that is to say, to provide for the photographicprinting of the objects carried by a line of character slugs, thecharacter slugs are releasedfromA the magazine 1 by the key-boardmechanism 2, the spacers from their magazines 3 by the key 4,' and aredelivered to the assembler 5. The assembler is then manually elevated bythe handle 6 and trips the delivery slide 7, whereby the composed lineis transferred from the assembler 5 through the intermediate channel 8,to the first elevator or line transporter 9. r1`he elevator thendescends and moves the line into position whereby the objects on theslugs can be photographically printed on a sensitized surface, or inother words, interposes the aligned slugs between the sensitized surfaceand a ligl'it source, but prior to the printing of the objects on ysaidsensitized surface, the line is justified, Jafter printing, the elevatorascends to its uppermost position and the line is removed therefrom bythe slide 10, to the transfer channel 11, from which the spacers arereturned to their magazine 8 and the slugs are lifted by the secondelevator 12 and deliveredto the distributing mechanism 13, whereby theyare restoredy to their proper channels in the magazine 1. rlhe parts sofaridescribed and their normal mode of operationform Wellknown elementsin linotype machine construction and it is thought unnecessary tospecifically describe the same.

y The main operating shaft for the mechanisms referred to in thepreceding paragraph is indicated at 14, but said shaft has omittedtherefrom the cam or other actuating means for a lead casting mechanismin view of the fact that such mechanism is dispensed with in a machinein accordance with this invention. The shaft 14, at the part thereoffrom which the cam or other actuating means for the lead castingmechanism is omitted, is provided with a series of adjustable actuatingcams, three in number, indicated at 15, 16 and 17, see Figure 36, andthe function of said cams 15, 16 and 17, as well as the mechanisms withwhich they associate, will be hereinafter referred to.

Arranged at the rear of the elevator 9 is what may be termed the mainhousing ,of the machine and which includes a vertically disposedintermediate portion 18, a rearwardly extending and upwardly inclinedupper end portion 19 and a rearwardly extending and upwardly inclinedlower end portion 20. The main housing is referred to generally by thereference character 21 and is rectangular in cross section at any pointthroughout its length. The front wall 22 of the intermediate portion 18of the housing '21 at a point between its transverse center and itsupper end` 1s provided with a light inlet opening 23, see Figures 3, 6,9 and 11. The rear wall of the intermediate portion 18 is provided witha removable section 24 so 1 the housing 21, each has a portion thereofshaped to conform to the o set portion and also to close the clearance26. Below the offset portion 25, the rear wall is provided with a pairof small apertures 27, see Figures 9 and 20, and below the apertures 27the said rear wall is provided with an enlarged opening 28 for thepassage of the endless conveyors of the conveyor mechanism to behereinafter referred to.

The housing 21 is anchored or secured in any suitable manner to themachine frame at the rear of the elevator 9.

A roll of fiexibie web is indicated at 29 and the web unwinds from theroll as indicated at 30. One face of the web 30 is provided with asensitized coating and said face is photographically printed upon in amanner to be hereinafter referred to. The web 30 is drawn through thehousing 21 and the movement thereof is intermittent and the manner ofshifting the web intermittently through the housing 21 will behereinafter referred to. The web 30 is constructed of l any suitableflexible material, preferably paper. The roll 29 vof web is carried by aspool 31 mounted on a spindle 32.

The web roll magazine-This magazine is employed for supporting the rollof web 29 above the housing 21 and it consists of a casing 33 having ahinged top 34 and a latch 35 for securing the top 34 in closed position.The magazine is constructed light proof.

The bottom 36 of the casing 33 is hinged,

' as at 37, to the rear wall of the upper end portion 19 of the housing21. The bottom 36 is furthermore provided with a passage 38 for the web30, and extending from the bottom 36, and registering with the passage38, is a collar 39, which when the casing 33 is secured in an uprightposition, will provide for 'the passage of the web 30 into the housing21, extends into the upper terminus r of the upper end portion 19 of thehousing 21 and frictionally engages with the inner face of said upperend portion 19; For the purpose of |maintaining the casing 33 in anupright position, the front wall 40 carries a spring latch 41 adapted todetachably engage with the machine frame. When the latch 41 is releasedthe casing 33 can'be swung to dotted line position, see Figure 3, andwhen the latch 35 is released the top 34 can be swung open, see dottedline position Figure 3, and entrance is had to the magazine for thepurposeof positioning a roll of web 29. Secured to the opposed sidewalls42 of the casing 33, is a pair of oppositely extending angle-shapedresilient supporting brackets 43, which are bifurcated for the receptionof the spindle 32 and which bears against the spool 31 to act as africtional gripping means to prevent revolving ofthe roll 29 when theweb 30 is not shifted intermittently through a means to be hereinafterreferred to.

The brackets 43 are secured to the side walls 42 by the hold-fastdevices 44.

The si al or alarm to indicate the breaking of t e web 30 as it unwindsfrom the roll 29 consists of a metallic guide roll 45, which isCournaled in the side walls of the upper en portion 19 of the housing 21and is arranged in proximity to the passage 38. The web 30 travelsagainst the roll 45. Leading from one end of the roll 45 to anelectrical source 46 is a conductor 47. The front wall of theintermediate portion 19 of the housing 21 is provided with a lug 48,carrying a' pivot 49, to which is electrically connected a circuitconductor 50 which leads to the source 46 and has interposed therein analarm 51. Carried by the pivot 49 is an arm 52 formed with a yoke 53, inwhich is pivoted a roll 54. Projecting from. the pivot 49 is a springcontrolled circuit opening and closing member which contacts with theroll 45 for the purpose of closing the alarm circuit. When the web 30 istaut, it bears against the roller 54 and shifts the pivot 49 in adirection so that the member 55 will be clear of the roll 45 and duringthe feed of the web 30, if the latter breaks, the tension applied to thearm 52 will be relieved, under such conditions the member 55 will beshifted by its spring to engage the roll 45 and close the alarm circuit.See Figures 3, 4 and 4a. When the alarm 51 is operated it will indicateto the operator of the machine that the web has become broken and shouldbe reset.

Arranged at the upper terminus of the intermediate portion 18 of thehousing 21 and in proximity to the front wall of said intermediateportion is a web guide roll 56. The web 30 travels under the guide roll45 and over the guide roll 56.- Positioned within the intermediateportion 18, at a point a substantial distance above and below theopening 23 is a pair of web guide rollers 57, 58. The web 30 travelsagainst the front of the guide roll 57 and under the guide roll 58. SeeFigures 3 and 9.

The shutter and its shifting o1- actuating mecham'sm.-See Figures 3, 6,8 and 16. The shutter is, employed for opening and closing the lightinlet 23 and slides against the inner face of the front wall 22 of theintermediate portion 18 of the housing 21. The shutter moves down toopenv and up to close the inlet 23. The shutter, see Figure 16, isrectangular in contour and consists of a pair of rectangular plates 59,60, the forlmer of greater width than and of the same length as thelatter. The plate 60 is permanently spaced from the plate 59 to providea light passage 61, and said passage 61 when the shutter is in positionto open the inlet 23 aligns with the latter. The plate 60 is adjustablerelative to the plate 59 to increase or decrease the width of thepassage 61 and for such purpose the plate 59 has projecting from itsbottom edge a pair of narrow spaced supports 62, 63, each formed with aseries of openings 61. rlille supports 62, 63, are flush with theforward face of the plate 59 but inset with respect to the rear face ofthe plate 59. The forward face of the plate 60, at each end terminalthereof is cut-away to provide a .shoulder 64 and to reduce thethickness of the end terminal portion, as indicated at 65. The shoulders64 abut against the inner edges of the supports 62, 63, and the shoulderis of such width that the forward face of the plate 60 will be flushwith the forward face'of the supports 62, 63. The openings 61, inconnection with the detachable securing means 66, are provided forsecuring the plate 60 in its adjusted position with respect to the plate59.

The shifting or actuating mechanism for the shutter consists of a shaft67 which extends transversely of the intermediate portion 18 of thehousing 21, and has one end thereof, as at 68, journaled in one of theend walls of the intermediate portion 18 and therefrom is a bearing 73for the end 69( of` the shaft 67. Fixed to the shaft 67, in proximity tothe opening 70, is a pinion 74, and fixed to the shaft 67, in proximityto the opening 71 is a pinion 75. Spacing-collars see Figure 36.

76 are carried by the shaft 67 and` interposed between the pinions andthe end walls of the intermediate portion 18. Stop collars 77 aresecured to the shaft 67 and abut against the pinions. l

The pinion 74 meshes with a rack78 secured to the rear face of the plate59 at one end thereof, and the pinion 75 meshes with a rack 79 securedto the rear face of the plate 59 nearv the other end thereof. When ltheshaft 67 is operated in a clockwise direction, the pinions 74, 75,engaging with the racks 78, 79 will elevate the shutter to close theinlet 23, and when the shaft 67 is operated in an anticlockwisedirection, it will shift the shutter downwardly to open the light inlet23.

The shaft 67 has its end terminal portion 69 provided with a crank arm80 to which is pivotally connected an actuating bar 81, see Figure 8,which has an offset portion 82, The offset portion 82 is pivotallyconnected, as at 83, to a spring cont-rolled shifting bar 84, travellingthrough a guide 85 and formed with a yokeshaped end 86 carrying a roller87, adapted to be engaged by the cam 15 to shift the bar 84 against theaction of its controllin spring 88, whereby the actuating bar 81 wi beshifted forwardly and operate the shaft 67 in an anti-clockwisedirect-ion, thereby lowering the shutter to open the vinlet 23 and toprovide for the aligning of the passage 61 with said inlet 23. After theroll clears the cam 15, the spring 88 acting on the yoke-shaped end 86of the rod 87 will shift the latter in a. direction opposite to that towhich it is shifted by the cam 15, and said rod 84 will carry theactuating bar v81 therewith operating the shaft 67 in a clockwisedirection whereby the shutter will be elevated or raised and the plateof the shutter will close the light inlet 23. The construction of thecam 15 is such. as to pro; vide for the shutter opening the light inlet23 a sufficient period to permit of photographically printing on the web30 and immediate-ly after printing the-shutter moves in an oppositedirection to close the light inlet. The shutter it temporarily heldstationar after it has been shifted to open the lig it inlet 23 and theconstruction of the cam provides for `this function.

Web pressing ami light cont-rolling mea-tam'am.-See Figures 3, 6, 8, 9,13, 14 and 15.` rThisv mechanism is provided for tightly pressing theweb 3() against the shutter to hold the web taut vand further forclosing the light source circuit immediately after the web is pressedtightly against the shutter, and said mechanism automatically moves frompressing engagement with the web and opens the light source circuitafter the print has been made. The said mechanismcomprises a flat plate89 of rectangular contour having a cushioning element 90 securedthroughout its forward face and said cushioning element bears againstthe web 30 to tightly hold the latter against the shutter. The upper andlower edges of the plate 89, as well as the element 90 are rounded, asat 91. Formed integral with each end of the plate 89 is a rearwardlyextending ear 92, provided near its rear end with a circularopening 93.The openings 93 in the ears 92 align with each other, and mounted ineach opening 93 is a circular disk 94 provided with a circumferentiallyextending groove 95. The disks 94 are rotatable within the ears 92 andsaid disks 94 are detachably connected to the ears 92 by coupling screws96 which extend into the grooves 95 of the disks 94. The manner ofsetting up the screws 96 with respect to the grooves 95 is that thedisks can slide on the inner ends of the screws 96. Each'of said disks94 is provided with an ecentrically disposed opening 97 and withthe'f'said o-penings 97 aligning with each other. Extending through thealigning openings 97, as well as bemg secured to the disks 94, is ashaft 98 having one end, as at 99, journaled in one of the end walls ofthe intermediate portion 18 of the housing 21 and its other end extendedfrom the other end wall of the intermediate portion 18 of the housing21, as indicated at 100. An enclosing cap 101 is provided for the end 99of the shaft 98 and a bearing 102 is provided for the end 100 of theshaft 98. The end 100 of the shaft 98 projects from the intermediateportion 18 of the housing 21 and is provided with a collar 103 carryinga crank arm 104, which is connected to an actuating rod 105. The collar103 carries a circuit opening and closing member 106 to which isattached a circuit conductor 107 of the light source. Secured to theintermediate portion 18 of the housing 21, below the end 100 .of theshaft 98, is a contact 108 to which 1s connected a circuit conductor 109of the light source. The arrangement is such that immediately upon theclamping or tight holding of the web 30 against the shutter, the member106 will engage the contact 108 and close the light or lamp circuit.

As the shaft 98 is eccentrically connected to the disks 94, which are inturn connected to the ears 92, it is obvious that when the shaft 98 isactuated through the medium of the rod 105, in an anti-clockwisedirection, the pressing element will engage the web and tightly hold itagainst the shutter and at such time the light or lamp circuit will beclosed. When the shaft 98 is shifted in a clockwise direction throughthe medium of the rod 105, the web pressing element will be shifted fromengagement with the web and the light or lamp circuit opened.

The rod 105 has an offset portion 106 which extends in an oppositedirection with respect to the offset portion 82, and said offset portion106 is pivotally connected, as at 107, see Figure 36, to a springcontrolled shifting rod 108, which slides through the guide 85 and isprovided with a yoke 109 carrying a roller 110, which is engaged by thecam 17. When the cam 17 engages the roller 110, the rod 108 is shiftedforwardly against theaction of its controlling spring 111, and said rod108 will shift the rod 105 forwardly whereby the shaftv98 will beactuated in an anti-clockwise direction. After the roller 110 clears thecam 17, the spring 111 will shift the rod 108 in an opposite direction,carrying the rod 105 therewith, thereby actuating the shaft 98 in aclock-4 wise direction and movinu' the pressing element from engagementwith the web 30 and further providing for the opening of the lightsource or lamp circuit.

Primary web feeding me07Lamsm.-See Figures 3, 6, 8, 9, 17 and 18. Thismecha` nism is provided for intermittently unwinding the web 30 from theroll 29 and acts on the web 30 to intermittently shift it the requireddistance to receive a print of the alivned slugs an to set up a spacebetween the print and the print to follow, or in other words, theshifting of the web is such to provide for a space between thesuccessive prints on the web. The mechanism includes a pair of feedrolls 112, 113, which are arranged within the intermediate portion 18 ofthe main housing 21, and the roll 112 extends into the clearance 26.Each of the rolls is provided with a rubber blanket or other grippingmeans, as indicated at 114. The rolls 112, 113 are arranged incloseproximity to the guide roll 58, and the webl 30 as it leaves said guideroll is extended rearwardly and then passes between the rolls 112, 113.See Figure 9. The roll 112 is carried by an actuating shaft 115therefor, and the roll 113 is secured to an actuating shaft 116therefor.

The shaft 116 is journaled in the end walls of the intermediate portion18 of the housing 21 and the shaft 116 projects from one of said wallsand carries on its projecting end a pinion 117.

The shaft 115 is journaled in the end walls of the intermediate portion18 of the main housing 21 and projects from each of said walls. One ofthe projecting ends, indi cated at 118, is provided with a triangularshaped cam 119 and with a pinion 120 which meshes with the pinion 117.The shaft 116 is driven from the shaft 115 through the medium of themeshing pinions 117 and 120. The other projecting end of the shaft 115,as indicated at 121, carries a ratchet wheel 122, which isintermittently rotated in a manner as hereinafter set forth, for thepurpose of intermittently rotating the roll 112, and owing to the meshedpinions 117 and 120, the roll 113 will be synchronously operated withthe roll 112, whereby the web 30 will be shifted the desired distance.

Loosely connected with the projecting end 121, of the `shaft 115, isacrank arm 123, provided lwith a pawl 124 for impartin intermittentimpulses to the wheel 122 w en the crank arm 123 is intermittent-lyoscillated.

The `extended end 121 of the shaft 115 is provided with a cylindricalsocket 124', into' which extends the inner end 125 of the enlargedportion of an adjusting shaft 126. The reducedl portion of said shaft126 is indiated at 127, and owing to the setting up of the shaft 126with the reduced portion- 127 a shoulder 128 is provided.

Mounted eccentrically on, as well as being keyed to the enlarged portionof the shaft 126, is a circular' disk 12,9, which is positioned in thelower circular end 130 of the crank arm 123. The disk 129 is formed withan eccentrically disposed opening 131 through which extends the enlargedportion of the shaft 126.

The disk 129 provides means for vertically (photographic i adjusting thecrank arm 123 to provide for regulatingthe ext-ent of the impulses ofthe ratchet wheel imparted thereto through the medium of a pawl 124.-The higher the crank arm 123 is adjusted the nearer the lower end ofthe pawl 124 will be positioned with respect to the arm, and, therefore,the stroke or impulse imparted to the wheel 122 will be of shortduration. The lower the arm 123 is adjusted the farther the lower end ofthe pawl 124 will engage the teeth of the wheel 122 with respect to thearm 123 and the impulse or stroke imparted to the wheel 122 will belonger, or in other words, the arrangement disclosed provides meanswhereby the length of the shift of the web 30 can be adjusted. f

Secured to that end wall of the intermediate portion 18 of the housing21, through which projects the end 121 of the shaft 115, through themedium of the holdfast devices 131, is the lower vertical arm 132 of anangle-shaped supporting bracket, and the latter includes a horizontallydisposed arm 133 which projects outwardly from the afm 132 and whichterminates in a vertical arm 134 of greater length than the arm 1 32.The arm 134 is provided with an` opening 136 in which is arranged abearing sleeve 137.. The shoulder 128 of the shaft 126 abuts against theinner face of the arm 134, and the reduced portion 127 of the shaft 126exterds through and projects from the sleeve 13 Mounted on the reducedportion 127 ofy the shaft 126, outwardly with respect to the arm 134, isa manually operated dial 138, which provides means for rotating theshaft 126, which carries the disk 129, and by such arrangement provisionis had for the adjusting of the crank arm 123. The dial 138 is slidablykeyed to the projecting portion 127 of the shaft 126'and is formed witha laterally projecting hollow cylindrical knob 139 to facilitate theturning of the dial 138 when occasion requires. rIhe dial 138 is formedwith an interiorly arranged annular shoulder 140 against which abuts acoiled controlling spring 141, positioned to surround the reducedportion 127 of the shaft 126. The spring 141 is confined on the reducedportion 127 through the medium of a headed retaining device 142, whichhas threaded engagement with the outer end of theA reduced portion 127of the shaft 126.

The inner face of the dial 138 is formed with a circular row of sockets143 and selectively engaging with said sockets is apin 144, whichprojects outwardly from the arm 134, and when the pin 144 is inengagement with a socket 143, the ldial 138 is retained in its adjustedposition.

The crank arm 123 is intermittently os-` cillated or rocked through themedium of an actuating rod 145, which is pivotally connected to theupper end of the arm 123, as indicated at 146.

When vertically adjusting the arm 123 to increase or decrease theimpulse imparted to the wheel 122, the dial 138 is shifted outwardly onthe reduced end 127 of the shaft 126 until the dial 138 is clear of thepin 144, and when cleared it can be manually rotated carrying the shaft126 and disk 129 therewith, therebl elevating or lowering the arm 123,depending in which direction the disk 129 is shifted. l

Thedial or dial plate 138 has its outer face provided with graduations147.

Seconda/1y web feeding or shifting/mecham'sm.-This mechanism not onlyprovides for the shifting of the printed web, but also for' operating aconveyor mechanism, which is employed for conveying ortransporting the'printed web to the developing and fixing mechanism of the apparatus.See Figures 6, 8 and 9; The said secondary web feeding mechanismcomprises a shaft 148, which eX- tends transversely of the intermediateportion 18 of the main housing 21 and opposes the opening 28. See Figure9. The shaft 148-is journaled in the end walls of the intermediateportion 18 and one end,l as indicated at 149, projects from one of saidwalls.

The shaftl 148 is providedwith a pair of spaced sprocket wheels 150, 151for intermittently operating the conveyor mechanism, and the latter hasmeans to be hereinafter referred to, for gripping the printed web andfor synchronously shifting it with the shifting thereof by the primaryweb feeding or shifting mechanism, or in other Words, the primary andsecondary web .feeding mechanisms synchronously operate for the sameperiod. The shaft 148 is provided with an actuating means and acontrolling or adjusting means for said actuating means and which are ofthe same construction as that referred to in connection with the shaft115 of the primary webfeeding mechanism, and, therefore, it is thoughtunnecessary to specifically describe the same. The said means referredto, which cooperates with the shaft 148, is referred to generally by thereference character 152, and the actuating rod for such means at 153.

The actuating rods 145 and 153 are operated synchronously from a.shifting rod 154, which is common to the said rods 145 and 153, SeeFigures 36 and 37. The rod 145 is provided with an offset portion 155,

and the rod 153 with an oifset portion 156,l

and the said offset portions are so shaped as to have the free terminithereof oppose each other. See Figure 36. The offset porl' tions 155,156, oppose the forward end of the rod 154 and are pivotally connectedtherewith, as at ,157. The rod 154 is spring controlled, isslidably-mounted in the 85and formed with a yoke 158 carrying a ide
